Brainliest!!!<br> Please help ASAP !
Semenov [28]

Answer:

Please see below :)

Step-by-step explanation:

y - 5 = -(x + 11) + 2

y - 5 = -x - 11 + 2

y = -x - 11 + 2 + 5

y = -x - 9 + 5

y = -x - 4

54x + 15 = -3(3y + 1)

54x + 15 = -9y - 3

54x + 15 + 3 = -9y

54x + 18 = -9y

-6x - 2 = y

y = -6x - 2

Please let me know if I've done anything wrong!

The answer would be be B
~~~~~~~~~~~~~~~~~~~~~~~
You first factor out 54 and thats 3^2 * 6

(The factor of a # is what you multiply to get the answer)

You then do the same to x^9 and y ^7

After that you should have square root of [3^2 * 6x^8 * xy^6 * y]

When you combine this you will get 3x^4 y^3 sqre root [6xy]

(3x^2a - 4y^a z^3a) ^2 ...?
shusha [124]
The answer is 9x⁴ᵃ - 24x²ᵃyᵃz³ᵃ + 16 y²ᵃz⁶ᵃ


(a - b)² = a² - 2ab + b²
(3x²ᵃ - 4yᵃz³ᵃ)² = (3x²ᵃ)² - 2 * 3x²ᵃ * 4yᵃz³ᵃ + (4yᵃz³ᵃ)² =
                         = 3²x²ᵃ*² - 2 * 3 * 4 x²ᵃ * yᵃz³ᵃ + 4²yᵃ*²z³ᵃ*² =
                         = 9x⁴ᵃ - 24x²ᵃyᵃz³ᵃ + 16 y²ᵃz⁶ᵃ
